Proactive Performance Optimization of IT Services Supply-Chain Utilizing a Business Service Innovation Value Roadmap

摘要

Business investment in IT is increasingly linked to IT delivering new or enhanced services that leverage the capabilities of the cloud. The challenge that IT faces especially in cloud environment, is to continuously assess and proactively optimize the performance and quality of supporting IT services being delivered. This evaluation must be performed in the context of the overall Service Level Agreements (SLA) of the composite application and subsequently, the underlying dynamic compound IT services. Our paper presents a proactive optimizer solution that provides on-going service improvement driven by the regular evaluation alternatives of the performance if individual services. Through a Business Service Innovation value roadmap, the Enterprise Architect can model and assemble candidate services for composite applications and automatically use tools to deploy and assure the performance of the composite application. Using our solution, over time the architect can manage the composite application by comparing the quality delivered against simulated alternatives and make recommendations for change. Consequently, using the solution presented in this paper, IT changes are aligned to the challenge to leverage the constantly improving quality of supply-chain IT service while maintaining or reducing costs.
